Equivalent carbon content - Wikipedia

The equivalent carbon content concept is used on ferrous materials, typically steel and cast iron, to determine various properties of the alloy when more than just carbon is used as an alloyant, which is typical.The idea is to convert the percentage of alloying elements other than carbon to the equivalent carbon percentage, because the iron-carbon phases are better understood than other iron ...

The carbon equivalent is an indicator expressing the critical cool-ing time required for a steel material to change into 100% marten-site. The carbon equivalent was initially used to express not the critical cooling time but the critical cooling rate 3), but it is presently used to express the critical cooling time because the cooling time

Greenhouse CO e, and Carbon

Carbon dioxide equivalent (CO2e) “Carbon dioxide equivalent” or “CO2e” is a term for describing different greenhouse gases in a common unit. For any quantity and type of greenhouse gas, CO2e signifies the amount of CO2 which would have the equivalent global warming impact.

to a carbon, we need to look at the atoms each carbon is bonded to in order to correctly identify if they are equivalent. The carbon of the methyl group is only attached to a carbon, but the carbon of the methylene group is attached to a carbon and oxygen.

Since its adoption by IIW, the equation has been incorporated into a number of material standards and codes, including EN 1011-2:2001 [2] (replaces BS 5135-1984 [3]) and in a modified form in AWS D1.1 [4], with a "+Si/6" term added to the equation.. Further development of Carbon equivalent formulae has taken place and several can be found in technical literature today.
